Hello, I have been trying for months to find out if there is an alternative to gypsum plaster for interior walls.
We currently live in a newly built house (gypsum plaster) and it always feels very, very dry.
I’m someone who is quite sensitive and notices these things.
Now I am considering using lime-cement plaster (a finer version) or lime plaster, and I am looking for other homeowners who have had issues with these materials.
I hope to get information here from people who do not have gypsum plaster in their living spaces.
P.S. I recently visited a newly plastered house (cold cement plaster) and I was able to breathe much easier.
However, I am still hesitant to give the “go-ahead” to my plasterer.

See Knauf Rotband. It’s a classic product that they like to use, or Knauf 75 machine plaster. This is traditional gypsum plaster, mineral-based, vapor-permeable.
K. Gypsum plaster is mineral-based and vapor-permeable?
Isn’t it basically the last resort… and just chemicals?
Lime, lime-cement, clay, and gypsum—all mineral-based and all vapor-permeable.
I’m not sure if certain types of plaster can actually have a positive effect on indoor air quality, and if so, how they achieve that, since they all absorb and release moisture. Especially with controlled mechanical ventilation, I wouldn’t be concerned about it at all.
If you like the specific surface texture and don’t plan to wallpaper or apply thick paint afterward, choose based on that. Otherwise, I would say the choice comes down to price and the preferred contractor.
Edit:
A neighbor has extensively plastered their whole house with clay plaster. That brown earthy tone creates a cozy atmosphere, and I like the natural rounded edges and corners from the application. However, after an evening with neighbors and a few cases of beer, the air doesn’t feel noticeably better than elsewhere.

Huh? Do you know what you're talking about? Of course, it is mineral-based and breathable, what else! Always has been. Gypsum. Check Wikipedia to see what gypsum is. No chemicals or anything like that.As I already mentioned... He writes in his first post that he has been researching for months and doesn’t even know what gypsum is.
Five minutes on Wikipedia and you’re informed.

Isn't it actually just the worst .... and only chemicals?Where do you get this nonsense from? Source? And why don’t you use a gypsum-lime plaster instead? For example, Knauf MP 75 G/F-Light
